GATE-VALVE.

Specification of Letters Patent.

Patented Aug. 8, 1905.

`citizen of the United States, residing at New York city, Brooklyn, county of Kings, and State of New York, have invented new and useful Improvements in Crate-Valves, of which the following is a specification.

This invention relates to a gate-valve more particularly designed for controlling the flow of yeast, zac., .from the fermenting vessel to the yeast-pocket of an apparatus for converting wort into beer. The invention is, however, also applicable to other vessels containing a Jfinely-divided material which is to be removed at certain periods.

In the accompanying drawings, Figure l is a vertical longitudinal section, partly in elevation, of my improved gate-valve, showing it applied to an apparatus for converting wort into beer; Fig. 2, an enlarged side View, partly in section, of the valve-actuating mechanism; Fig. 3, a horizontal section on line 3 3, Fig. 2; Fig. A, a longitudinal section through the valve proper; and Fig. 5, a horizontal section on line 5 5, Fig. 4.

The letter a represents a fermenting-tub having a tapering bottom a', which is provided with a threaded cylindrical neck a2. Into this neck is screwed a threaded ring the upper beveled edge of which constitutes a valve-seat. To a lower flange b2 of ring Z) is attached the yeast-pocket c. Communication between tub a and pocket c is controlled by a vertically-movable gate-valve d, which is adapted to engage seat Zi and which plays within tapering bottom o. The upper side of valve d is coniform and tapers in a direction reverse to that of the bottom, so as to prevent a deposit of sediment upon the valve. From the valve depend a number of guide-pins d', movable along the inner side or' ring b and connected at their lower end by a spider d2. The pins d have an acute angular outer contact edge, Fig. 5, which prevents yeast, &c. from settling between valve-seat and pins.

The means for operating the valve CZ are as follows: From the top of the valve project a pair of lugs d3, bridged by a pin Z4 to constitute a bail. Between this pin and the apex of the valve enters the upper curved arm of a bent rod or lifter e, the vertical shank of which passes outward through the bottom a and through a stuiiing-box f, containing a suitable packing f. The lower threaded end c of rod e carries a nut g, having a circumferential groove g. Vertical movement of this nut is prevented by a bail 7L, depending from stuiing-boxf and having a lower notched base it', that enters groove g. Rotation of rod c is prevented by feathers h2, secured to bail /t and engaging grooves e2 of the rod, while the upward movement of the latter is limited by a head c3. A rotation of the nut g will either raise or lower lifter c to correspondingly open or close valve d, which is suspended from the lifter. By the construction described any clogging is prevented, and as the valve plays within the tub itself the height of the apparatus is considerably reduced.

The outlet c of pocket c is controlled by a valve z', which may be similar in construction and mode of operation as valve d.

What I claim is- The combination of a coniform gate-valve with pins depending therefrom and having outer acute angular contact edges, a ring having an upper valve-seat and adapted to be engaged by said contact edges, and means for raising and lowering the valve, 'substantially as specified.

Signed by me at NewYork city, (Manhattan,) New York, this 31st day of January, 1905.
